In the arrangement shown in figure, the mass of ball 1 is (n = 1.8) times larger than that of rod 2. The length of rod is l = 1m. The ball is set on the same level as the lower end of the rodand then released, find the time taken by the ball to reach at the level of the upper end of the rod. The masses of pulleys, threads and the friction may be neglected.
